In accomplishthe same, exercise a corresponding effect ing this we detachably mount upon the orupon the interior thereof, so that we are dinary press roll of this machine, a smooth enabled to produce in this manner a paper or seamless or the like metal tube having tube of a desired large diameter and of the an internal longitudinal key engaging the requisite rigidity and strength, perfectly corresponding and well known groove in the cylindrical with the desired smooth or periphery of the press roll, whereby the two glazed surfaces throughout, and capable of I 0 revolve integrally. being adapted for use in the construction of The press-roll with its surrounding tube sliver cans of the kind desired. are of such a diameter that the paper tube The rolling of the paper tube as aforesaid, to be formed thereon, will possess the interloosens the tube upon its support, so that nal diameter desired.

It will be obvious that the wet web may be run directly on to an arbored drum or roller instead of a tube mounted thereon, but this method is not so economical.

Referring to the drawing in which similar letters refer to similar parts throughout theseveral views, A is the paper tube made of a number of concentric layers of a wet paper web wound upon a detachable tube B also keyed or otherwise secured to the press roll G for the two to revolve integrally. D is the well known cuttingtubeand a seamless metal groove formed in C andwith which engages a key E upon the tube B to ensure their integral rotation as aforesaid. F is the polishing roller held in frictional engagement with the exterior of the tube A, by the crossslide G of the movable saddle H of an ordinary lathe IQ or the like.

\Vhat We claim as our invention and desire to secure by Letters Patent, is V l. The process of making seamless tubes which consists in concentrically Winding a number of layers of wet paper pulp around a tubular member allowing the pulp to dry, and bringing the pulp tube so formed into frictional engagement with member, whereby the pulp tube is simultaneously polished and loosened from the tubular member.

2. The process of making seamless tubes which consists in concentrically winding a number of layers of wet paper pulp around a tubular member and allowing them to'dry thereon; when in a dry state and during the rotation of the tubular member,'bringing a rotatable member into frictional engagement with the said pulp tube whereby the latter is simultaneously polished and loosened from the tubular member; and applying a seamless metal rim at one end of the pulp site end of the pulp tube.

In testimony whereof we have signed our names to this specification.
